Abstract

Purpose

Due to the extreme importance of evaluating the credibility of information available on a huge number of scientific websites, the present research aimed to develop a measurement scale based on a validated questionnaire incorporating the novel conceptualization of the concept credibility by Hovland and Weiss (1951).

Design/methodology/approach

Regarding the descriptive and survey nature of the research, the data were collected based on a stratified random sampling among the 672 students in two different contexts at five top nonmedical universities and, with a one-year interval, at three top medical universities in Iran. High reliability and construct validity were reported by testing the convergent and discriminant validity of the main instrument.

Findings

Confirmatory factor analysis (CFA) resulted in a scale named SWCRED including eight components and 28 items. Considering path coefficients (?) and t-statistics (t-value), a significant relationship was reported between all components and the main variable of credibility in the final scale at a 99% confidence level (t = 2.57).

Practical implications

Results suggest that the information credibility of scientific websites, especially in the university contexts, can be measured by asking participants to rate how well eight components represent content including ethics, writing style, website appearance, website identity, professional information, accuracy, usability and interaction. The scale has a goodness of fit from the different indices and is of high validity for use in different educational and research settings.

Originality/value

The framework underlying the research has the required quality integrating a set of most important criteria for exploring the credibility evaluation of scientific web information by the students, which is useful for future-related studies.

Abstract

Purpose

User behavior in online information evaluation is the result of a multitude of factors related to social, cultural, personal and psychological issues. The present study aimed to examine the effects of three important psychological variables including personality, self-efficacy and attitude on online information evaluation.

Design/methodology/approach

Four validated measures were administrated in person and online among 355 postgraduate students at Shahed University, Tehran, Iran. For testing the possible relationships among the variables, the reliability, normality and Pearson correlation tests were performed by using SPSS 24.0. Moreover, to test the ten hypotheses of the research, the structural equation modeling was considered using AMOS 26.0.

Findings

The findings confirmed the first five research hypotheses indicating the direct positive relationships among the four variables except for the impact of self-efficacy on attitude. The mediated effects of the variables were not supported except for the mediating role of attitude in the impact of personality on online evaluation behavior. The variable personality was found to be fundamental among the tested paths because it influenced the information evaluation behavior, both directly and indirectly.

Originality/value

The study showed the impacts of the three variables, which demonstrates that online information evaluation is greatly affected by psychological factors.

Abstract

Purpose

Due to their unique characteristics in terms of information type, quantity and exchange, social media are regarded as a challenging information resource that makes credibility evaluation a more complicated behavior. This study aims to investigate the role of media literacy in the credibility evaluation of social media information among students as a major community of user groups.

Design/methodology/approach

The study tried to explore whether or not the three popular platforms of WhatsApp, Instagram and Telegram with their unique features, show a significant difference in the credibility evaluation among a sample of 150 students at the Shahid Beheshti University, Tehran, Iran. By administrating two validated measures related to the two main variables, data gathered were analyzed through the partial least-squares (PLS) method using the software SmartPLS.

Findings

Convergent and discriminant validities, as well as model fit indices, showed the reliability of the conceptual model at the 99% confidence level. Moreover, path analysis demonstrated that media literacy could affect all components of the credibility evaluation, except for currency evaluation. Overall, media literacy had less impact on evaluating information sources and information credibility compared to information presentation. Further analysis showed no significant difference in credibility evaluation with respect to the application used.

Originality/value

There appears a crucial need for the students to be skilled more in evaluating content and source without which their decision-making might be negatively affected.

Abstract

Purpose

The study aims to investigate the role of information literacy competencies regarding the impact of personality factors on knowledge sharing behavior in information services.

Design/methodology/approach

A sequential mixed-methods approach was used as the research design. To construct the two less identified variables of knowledge sharing behavior and information literacy competencies in actual information services, the literature existed were searched and validated in a systematic review procedure. Two conceptual models including two initial questionnaires were developed, which were then confirmed by a set of 10 related experts through semi-structured interviews. For gathering data related to the variable personality factors, the Five-Factor Inventory was used as a widely recognized measure. The sample population of the quantitative section constituted of a set of 160 librarians working in the central libraries of the state universities located at Tehran, Iran. Data analysis was conducted through structural equation modeling using software SmartPLS.

Findings

The results showed that the personality factors had a positive and significant impact on information literacy competencies with a path coefficient of 0.48 and information literacy competencies skills had a positive and significant effect on the knowledge sharing behavior with a path coefficient of 0.47. However, with a path coefficient of 0.02, the personality factors had no direct effect on the knowledge sharing behavior while its indirect impact was then confirmed by the mediating role of information literacy competencies.

Originality/value

To achieve the desired knowledge sharing behavior, there should be concerns about the information literacy competencies of the librarians. Moreover, the knowledge sharing behavior of the librarians should be more taken into consideration concerning their personality factors.

Abstract

Purpose

Social media pose serious challenges to information evaluation, which can make credibility evaluation more difficult compared to other information resources. As a result, this paper aims to explore related challenges and research directions to put forth a set of criteria practical for actual users in their decision-making.

Design/methodology/approach

Related literature in such disciplines as information, communication and media sciences were carefully searched and assessed. Once challenges and research directions were identified, a literature coding approach was considered to design a conceptual framework incorporating the main criteria used for evaluating information found from social media.

Findings

Some areas of consideration such as political concerns, health information, organizational issues and purchasing behavior are among the main challenges inevitable in evaluating current social media information. The relative importance of credibility criteria varies from study to study depending on factors such as the characteristics of the participants, the type of the source and the type of information.

Practical implications

A conceptual framework developed including four main dimensions of the information source, information presentation, information credibility and decision-related issues as a set of criteria useful for the decision-making of social media users when evaluating information.

Originality/value

The literature review and the conceptual framework incorporate a set of most important criteria for exploring the credibility evaluation of social media information, which are also useful for future related studies.

Abstract

Purpose

The purpose of this paper is to explore the possible relationship between knowledge management infrastructures (KMI) and organizational intelligence (OI) in two country-wide research centers dependent to Ministry of Science, Research and Technology, namely, Iranian Research Institute for Information Science and Technology (IRIIST) and Institute for Humanities and Cultural Studies (IHCS).

Design/methodology/approach

The research is a survey in a descriptive manner. Using two validated questionnaires related to KMI and OI, the research was conducted among 175 faculty members and staffs of the two research centers. Using structural equation modeling (SEM) procedures, collected data were then analyzed by software SPSS and partial least squares.

Findings

Factor analysis showed a high factor loading related to the two main variables and all of the items indicated goodness of fit (GoF) related to the questions. The variance-mean ratio between two variables was higher than 0.5 indicating a high convergent validity. R2 for OI showed fitness of SEM. The GoF for IRIIST was 0.642 lower than IHCS with 0.645. Also, path analysis indicated a significant relationship between two variables by 95 percent degree of confidence accepting the two research hypothesis.

Originality/value

By comparison, KMI was more correlated with OI in IHCS than IRIIST. KMI in IRIIST predicted OI by 0.826 percent while in the IHCS by 0.848 percent.

Abstract

Purpose

Due to the lack of standard and research-based frameworks in evaluating the content designed in electronic courses, there appears a need to examine some existing theoretical models like the cognitive theory of multimedia learning (CTML) developed by Richard Mayer on real occasions. To confirm the effectiveness of the seven principles of the model driven from this theory in different educational settings, especially amid the COVID-19 pandemic, the present study was conducted in the contexts of two universities in Iran for comparison purposes.

Design/methodology/approach

The present research is a descriptive one for which a survey method was considered to collect data. A measurement instrument was developed based on the seven principles mentioned in the last edition of the book written by Clark and Mayer (2016) as well as an extensive review of the related literature. The data gathered from 524 online questionnaires returned by students of a public university Shahid Beheshti University (SBU) and a private one Ruzbahan University (RU) were then analyzed through partial least squares using SmartPLS 3.0.

Findings

The results of confirmatory factor analysis showed that convergent and discriminant validities, as well as model fit indices, had the reliability of the theoretical model at the 99% confidence level. Based on the path coefficients found for testing hypotheses, modality and coherence principles were the first and last priorities, respectively. Moreover, the comparative study showed that t-statistics values for multimedia, contiguity, modality, redundancy and personalization but not for coherence, and segmenting and pretraining principles are significantly different between the two universities.

Originality/value

This study can be considered a pioneering research in Iran so as to increase the quality of multimedia design, instruction and learning at university levels in future research while emphasizing the importance of Mayer’s principles in the design of electronic content.

Abstract

Purpose

Using asymmetric impact–performance analysis for examining an asymmetric relationship between user satisfaction and website features, the present research aims to identify features of high priority for quality improvement. For doing so, the current research was conducted in the context of the E-learning website of the most prestigious university in Iran, namely, the University of Tehran.

Design/methodology/approach

The main question was which of the three groups of basic, performance and excitement factors has the required dimensions of the quality of the website based on the model WebQual 4.0 by considering Kano’s user satisfaction model and impact–performance analysis. This is a descriptive survey, applied and cross-sectional study. The study population included Tehran University’s students who enrolled in virtual courses in the academic year 2020–2021 from which a sample of 457 students was selected. The data collection tool was the questionnaire of Webqual 4.0, as well as a researcher-made questionnaire to measure end-user satisfaction.

Findings

Using structural equation modeling and multiple regression, the findings showed that the customer’s overall satisfaction with the mentioned website is primarily affected by the feature interaction with services, including the two structures of trust and empathy, and then the dimensions of usability and quality of information. Examining the Webqual 0.4 dimensions indicated that the website usability dimension is a part of the high-performance excitement factors group, the information quality dimension is a part of the high-performance basic factors group and the website interaction dimension is in the low-performance basic factors group.

Originality/value

The research is highly innovative taking the theoretical model of Kano and methodological investigation of asymmetric impact–performance analysis into consideration alongside the WebQual 4.0 as a fundamental model for website assessment. Moreover, the research was conducted on an E-learning website, which is unique and a necessity amid the COVID-19 pandemic.

Abstract

Purpose

This study aims to evaluate the selected children’s websites in terms of information visualization features based on the criteria existing in the related literature and expert scrutiny.

Design/methodology/approach

A mixed-methods (qualitative-quantitative) study was conducted with a descriptive-comparative approach. A set of 80 English websites, as well as 24 quality Persian websites, were selected constituting a sample size of 104 websites. A conceptual model was developed from an extensive literature review on information visualization in children’s websites. In the quantitative part, a checklist derived from the conceptual model and based on the heuristic evaluation method was distributed among 20 related experts, the data of which were then analysed through Partial Least Squares using SmartPLS 3.0.

Findings

Confirmatory factor analysis showed high-reliability indicators and fit indices in measurement and structural models showing that the conceptual model had the necessary validities among the expert evaluators. Path coefficients showed that layout design and user interface design were the first and last priorities among the dimensions. It was also found that English websites were much more successful than Persian websites in supporting the features of information visualization.

Originality/value

The current study has implications for the effective use of standard features related to information visualization in children’s websites usable for designers, media specialists, parents, instructors and librarians, which would also make the children more engaged to better use, learn and interact with the websites.
